Of Wyoming's three largest towns, Casper has the highest Irish population with 13.56%. In Cheyenne, 12.72% of residents are Irish. Excluding students at the University of Wyoming, who aren't counted in census surveys, Laramie's Irish population is 11.83%.

Of course, we're all Irish today. So, enjoy a green beer (or several) and have a shamrocking St. Patty's.
